iControl.CommonIPPortDefinition[][]

Hmm, C is not my strong suit either, but try this:

 

 

members_to_remove[0][0].member.address = "10.10.10.10";

 

members_to_remove[0][0].member.port = Convert.ToInt32("80");

 

Do you mind posting your solution? Even if you answered your own question?

You'll want something like this:

 iControl.CommonIPPortDefinition[][] members_to_remove = new CommonIPPortDefinition[1][];   
  allocate first dimension to a 1-d array for the 2nd dimension.  
 members_to_remove[0] = new iControl.CommonIPPortDefinition[1];  
  allocate the second dimension element to a new IPPortDefinition structure.  
 members_to_remove[0][0] = new iControl.CommonIPPortDefinition();  
  add values  
 members_to_remove[0][0].address = "10.10.10.10";   
 members_to_remove[0][0].port = 80;
